Login to mobile banking app with my fingerprint?

Last Edit: 06/11/18

Some UK banks, most notable Natwest and HSBC, do allow customers to login
to their account with their fingerprint. The requirement for the customer
is to have either an Android or Apple smartphone, and the banks mobile app
(software application) installed on it. The Apple or Android smartphone will
also need to have the following software installed on it:

Apple Touch ID
and typically an iOS (operating system) version of 8 or higher.

Android Fingerprint and typically an OS (operating system) version
of 6 or higher.

Setting up a biometrics fingerprint login will differ with each banking app
-- the Natwest app can be downloaded from the Google store -- but, judging from
instructions published online by the banks, the process looks to be straightforward,
and is simple a matter of selecting the option of either logging in with a fingerprint
or a passcode.
